I had never used a polarizer filter before and now I am kicking myself for not taking a photography class in high school. This thing works wonders at reducing glare on a watch crystal when taking pics. It doesn't seem to really impact the colors negatively at all but if you rotate it around you drastically reduce or eliminate the glare on the watch glass in your pics.

Comes packaged in a nice carrying case that isn't small but is secure and will protect this lens. Also include two individually sealed and wrapped microfiber towels for cleaning it when needed. I look forward to trying this lens on some outdoor water shots later this year but it will be a permanent addition to my photography bag on any and all watch shoots in the future for sure. Very happy with this purchase!

Good quality and reasonable price. Comparable to Tiffen Hoya Nisi all of which are much more expensive. I would say slightly better than Tiffen and Hoya. Tiffen silver ones - digital HT are marginally better however.

Nice and clear with good results in lots of different lighting. Some marks to show shade/filter intensity would be nice so you can have a quick reference for where you are on the scale, great otherwise though.

Bought this filter to learn how polarizers work. Was very impressed with the case the filter came in. Wish I could buy these cases empty to package my other filters!

It does a good job.

I’ve not owned a dedicated camera in about 30 years. I always had some kind of protective filter on SLRs I previously owned. So, seemed like the thing to do with our new mirrorless camera. Took a couple of photos at the Bass Pro Aquarium and it looked like I was in the water with the fish. No reflection from the glass so I guess this filter works.

I'm far from being a pro in photography, I shoot as a hobby with a Sony RX10 Mii, so these filters, the polarizer and the variable ND do an excellent job for me. They're not the top of the line, but, for sure, they're also not bottom. The polarizer does its job in cutting reflections, and the ND does a good job in cutting off the quantity of light entering the lens.
The built quality is good, easy to screw them on/off, not to stiff and to to lose when rotating. All in all, in my opinion, a good investment.

Bought it for a job to eliminate reflections and worked amazing.
